Abstract

An expression is obtained for the depth of penetration of an electron beam in terms of the thermal conductivity of the solid and other parameters of the material. In the case of a moving beam, the penetration decreases with speed; an expression for the decrease of penetration is obtained in terms of the thermal diffusivity. An electron beam technique is described which may be a useful method for measuring thermal diffusivities.
